Advantages |
Disadvantages |
Liquid-to-Air,
Non-refrigerated |
|
- Highly efficient
- Economical
- Simplest design
|
- Dissipates heat into room
- Primary recirculated coolant is always above ambient air temp
|
Liquid-to-Liquid*
Non-refrigerated |
|
- Quiet operation
- Simplest design
- Most Efficient
- Cooling tap water is drawn only as needed
|
- Primary recirculated coolant is always above secondary water temp
- Availability of tap/facility water
- Cost of tap/facility water
|
Liquid-to-Air,
Refrigerated |
|
- Best temp. control
- Primary liquid is brought below ambient air temp.
|
- Dissipates heat into room
- More expensive than CU/CUW type
|
Liquid-to-Air,
Refrigerated Split
System |
|
- All advantages of one piece RU series
- Heat is expelled outdoors
- Quiet operation
|
- Set-up cost
- Typically more expensive than one piece RU series
|
Liquid-to-Liquid*,
Refrigerated |
|
- Best temp. control
- Quiet operation
- Primary liquid is brought below secondary (tap) water temp
- Cooling tap water is drawn only as needed
|
- Availability of tap/facility water
- Cost of tap/facility water
- More expensive than CU/CUW series
|
Air Circulating/
Cooling Unit |
|
